Deeside bashing is a car killer :scared: Keep the pics coming, will be an interesting thread :cool:
 
heres a few more pics, i found the exhaust header was 2mm smaller than the exhaust port i,ve now matched it and smoothed all the ruff edge,s, the head transfer ports were ruff to say the least so used a 3mm grinding globe to take the surface off then polishing head to get them smooth then braso metal polish to finish them off, done the same on exhaust port, but not touched the inlet port thats has to be slightly ruff so i,ve read god nows why??
